Waste-to-Energy systems employ a combination of mechanical, biological or chemical processes to recover the energy stored in waste. The simplest process is incineration. Incineration is the direct combustion, or burning, of relatively unprocessed waste to produce heat and boil water. This produces steam, which powers turbines that generate electricity. Incineration is also the oldest process for deriving energy-from-waste. Concerns about the direct combustion of waste include efficiency rates, flue emissions, post burn residues, storage of the energy produced, and loss of valuable recyclable commodities.
Modern waste conversion technologies are increasing the energy recovery rates from waste, reducing emissions, reducing residues, producing fuels that can be stored more easily as well as for longer periods than electricity, and inherently recover recyclables. Waste conversion technologies; convert waste into fuels such as syngas, methane, methanol, cellulosic ethanol, biodiesel, other biofuels, other second generation liquid transportation fuels, or pellets. These technologies include gasification, plasma gasification, plasma arc gasification, torrefaction, pyrolysis, thermal depolymerization, anaerobic digestion, mechanical biological treatment (MBT), and fermentation. Processing and preparing the waste stream prior to its conversion to fuel is an integral part of advanced Waste-to-Energy plants.
Vecoplan delivers turnkey systems that process waste as a feedstock for the production of alternative fuels and energy. The equipment included in our systems is determined by the composition of the waste feeding into the system and the specifications required on the material that feeds out. Machinery and technologies available from Vecoplan for waste-to-energy prep systems includes: Receiving stations, Primary size reduction, Screening, Air classification, Metals separation, Optical sorting, Secondary shredding, Storage, Testing, Metered feeding, Conveying between workstations, and Integrated controls for the entire system. Most systems employ some, but not all of these. Knowing which to specify and how to incorporate the best technologies to get the job done is the key to success. Vecoplan has this expertise.
Vecoplan has experience in the design, engineering and construction of machinery and systems for commercial, industrial, and municipal waste-to-energy plants. Our systems operate in municipal facilities for the production of liquid transportation fuels from MSW (municipal solid waste) residuals. We have equipment used in factories that process paper and plastics waste to produce alternative fuel pellets. Vecoplan machinery is incorporated into plants that convert agricultural wastes, such as corn stover, into cellulosic ethanol. Cement plants use Vecoplan (RDF) refuse derived fuel systems to produce fuel for their kilns. Some of the worlds largest wood pellet factories use Vecoplan machinery, also. Bottom line - no matter what type of waste you’re talking about or what kind of fuel you’re making, no one can match the experience that you get with Vecoplan.
